Global Class Change: From the Start, I Rewrite Fate and Draw a Chosen One

[Everyone Changes Class + Passionate Battles + Absurd Humor + Multiple Classes + Leveling Up + Dungeons + Lucky Draws!] In a world where everyone changes class, people scramble to get combat classes. But with odds this damn ridiculous, even though everyone can draw cards, getting a combat class is practically a pipe dream! And that's not even counting the extremely rare classes! Sun Sheng, one of the new generation's high school graduates, awakens black source energy and becomes "the world's outcast." But somehow, he draws the one-and-only class in the world: [Heaven's Chosen]! [Immobilization Spell] and [Shelter Spell] are only basic techniques! [Bronze Head, Iron Wall] and [Gather Form, Disperse Qi] are a piece of cake, too! [As chaos first dawns, the spirit ape slips away; the Great Sage Equal to Heaven awakens in battle!] Years later, with tens of millions of abyssal monsters bearing down on them, everyone is driven to the brink. Sun Sheng transforms into a giant ape, grips the Ruyi Jingu Bang, and stands before the countless masses! "If you monsters dare attack, your Grandpa Sun will make sure you never leave alive!"
